Description

Bio-contact oxidation filtering settling pond
Technical field
The invention belongs to water pollution control and prevention and control field, particularly to administering method and the facility of a kind of sewage and polluted water body.
Background technology
Water is Source of life, along with the development of industrial or agricultural and the tertiary industry, water resources shortage and water pollution problems become the bottleneck of social development. The pollutant in sewage are removed by current topmost water pollution control measure Shi Jian sewage treatment plant, and sewage treatment plant mainly includes city centralized wastewater treatment factory and each polluter decentralized wastewater treatment plant.
The sewage treatment facility that biological contact oxidation pond, Aeration tank, sedimentation tank and filtering ponds Deng Shi sewage treatment plant are common, in existing sewage treatment project, these facilities mainly occur with separate structures, owing to these facility function singlenesses, treatment effeciency is limited, sewage is between structures conveying capacity are big, cause that existing sewage treatment project floor space is big, energy consumption is high, investment and operating cost higher.
Also having biological contact oxidation pond to hold concurrently Aeration tank in existing sewage disposal technology, filtering ponds are held concurrently the design of sedimentation tank, but the design merging above-mentioned all facilities not yet occurs. Particularly second pond, its effluent quality is directly by the impact of mud sedimentation effect, and disturbance produced by aeration, whipping process directly influences the sedimentation effect of mud, thus secondary clarifier effluent water quality can be affected, therefore, it is difficult to the compatible sewage treatment facility such as Aeration tank, biochemical reaction tank.
Biological contact oxidation pond, Aeration tank, filtering ponds and sedimentation tank are combined by the present invention cleverly, effectively improve sewage treating efficiency, save investment and the operating cost of sewage disposal.
Owing to the pollutant levels of the water bodys such as contaminated river, lake, pond are relatively low, generally good than existing sewage disposal plant effluent water quality, be not suitable for adopting existing treatment measures to purify. And it is relatively low easily to there is dissolved oxygen concentration in some solid contaminant water body simultaneously in these water bodys, the problem such as serious appearance black and odorous water. The present invention, by removing the solid contaminant in the water bodys such as river, lake, pond with less investment and operating cost, increases the dissolved oxygen of its water body simultaneously.
Summary of the invention
For improving the treatment effeciency of sewage treatment facility, reducing energy consumption, minimizing investment and operating cost, the present invention proposes bio-contact oxidation filtering settling pond, biological contact oxidation pond common in sewage disposal, Aeration tank, sedimentation tank and filtering ponds is organically merged. Bio-contact oxidation filtering settling pond is mainly made up of cell body, aerating system, filtration system and collecting system etc., wherein filtration system is wrapped on net cylinder by filter cloth and makes, be easy to bio-film colonization at packing materials such as filter tube surface configuration elastic filler, soft-filler, combined stuffings.Sewage enters subsequent processing or water outlet up to standard in above-mentioned facility after biochemical degradation and filtration precipitation, refluxes or remove after sludge settling.
The present invention is used for purifying sewage and is implemented by following technical proposals, comprises the steps:
1) aeration
Arranging aerating system in cell body, for sewage oxygenic aeration, sewage occurs aerobic biochemical to react in cell body;
2) filter
Cell body water level is higher than the water level of collecting system, and sewage enters collecting system through filtration system, and solid contaminant is trapped within cell body and biochemical reaction or precipitation occur, and clear water enters collecting system;
There are the anaerobic biochemical reaction a part of pollutant of degraded in sewage in filtration system;
3) precipitation
The pollutant that filtered system retains occur aerobic biochemical to react in cell body, and solid contaminant concentration increases, and solid contaminant is by precipitating or float removal;
4) water outlet
Clear water enters collecting system by filtration system, and clear water absorbs the oxygen in air increases dissolved oxygen, and aerobic biochemical reaction occurs, further the pollutant in degraded clear water.
The present invention processes sewage, provides the benefit that compared with prior art:
1) biological contact oxidation pond commonly used in sewage treatment project, Aeration tank, sedimentation tank and filtering ponds are organically merged by the present invention, save the area, reduce energy consumption, reduce investment and operating cost;
2) owing to the present invention adopts filtration water outlet, sedimentation effect is little on effluent quality impact, can arrange the facility such as aeration, stirring in cell body, makes cell body use as aerobic biochemical pool;
3) filtration system of the present invention is combined by biomembrane, filter cloth and net cylinder, primary filtration media is biomembrane, formed by bio-film colonization, biomembrane is a Biochemistry Reaction System inherently, biomembrane automatically generates and updates compared with existing synthetic filter membrane, simultaneously can also degradation of contaminant;
4) filtered system intercepts and is concentrated in cell body in the sewage in cell body, it is simple to focus on; Pollutant levels in cell body are high, and cell body volumetric loading is high, and rate of contaminant degradation is fast;
5) biomembrane that the present invention uses as filter medium is also anaerobic biochemical reaction system simultaneously, and sewage is being degraded through pollutant such as COD, BOD, ammonia nitrogen, total phosphorus in biomembranous process;
6) compared with existing biological contact oxidation pond, aeration turn plate etc., in biomembrane of the present invention, the pollutant of biochemical reaction degraded are that the overwhelming majority is at pond vivo degradation for a small amount of pollutant in water outlet, it is simple to improve treatment effeciency, improve outlet effect;
7) in cell body, hydraulic detention time, pollutant burden, sludge bulking etc. are less on the impact of effluent quality of the present invention, and therefore the ability of the present invention water-fast stroke load and water quality impact load is stronger;
8) clear water is fully contacted with air in the net cylinder inland river collecting system of filtration system, forms the reaction of substantial amounts of dissolved oxygen generation aerobic biochemical, makes clear water sustaining degradation pollutant after leaving apparatus of the present invention;
9) aerating system is set in cell body, aerobic biochemical reaction is there is in sewage after entering cell body, by the biomembrane generation anaerobic biochemical reaction of filtration system, enter collecting system generation aerobic reaction, in a set of facility, concentrate the biochemical reaction technique completing " aerobic+anaerobism+aerobic ". The anaerobic treatment facilities such as anaerobic tank, methane-generating pit and anaerobic pond were set before the treatment facility of the present invention, sterilization even depth treatment facility are set afterwards, different process requirements can be met;
10) owing to the pollutant levels of the water bodys such as contaminated river, lake, pond are relatively low, generally good than existing sewage disposal plant effluent water quality, be not suitable for adopting existing treatment measures to purify.And the pollutant that the filtration system of the present invention can make sewage are concentrated, it is easy to after concentration focus on, it is suitably arranged on river course for river regulation, being suitable as preposition pond to purify for the water inlet in emphasis lake, major river valley and marine site, the infiltration structures being suitable as water intake facilities improve water intaking water quality;
11) the filtration system top arranged at vertical arranges chimney filter cap and prevents impurity entrance collecting system.
